The stability of I-girders during erection can be difficult to assess because of the limited presence of bracing and uncertainty in the support conditions of the girders. The behavior of curved girders during the early stages of construction is complicated because the curved geometry can lead to significant torsion. This paper highlights results from a research study that included both field monitoring and parametric finite-element investigations. Curved I-shaped girders were instrumented and monitored during lifting to provide data to validate finite-element models. Both rotational displacements and stress were measured during the lifting process. In this paper, the writers compare data collected from field tests with results computed from detailed finite-element simulations. A prismatic and a nonprismatic girder (with two different cross sections) were considered in the investigation. The I-girders experienced both rigid body rotation and cross-sectional twist. Additionally, the torsional warping stresses were observed to be of the same order of magnitude as the strong-axis bending stresses. However, it should be noted that the total stresses were well below yielding. The fact that the stresses are low during lifting should not be confused with a noncritical stage in the safety of the girders. Although the applied stresses are low, the stresses necessary to buckle the girder or to cause large deformations are also relatively low because usually no bracing exists and limited restraint is provided to the girders during lifting. The finite-element models were able to capture the measured behavior accurately, providing insight into appropriate assumptions and critical features for modeling curved I-girders during lifting. © 2012 American Society of Civil Engineers.

Excessive stay cable vibrations can cause severe problems for cable-stayed bridges. In this paper a semiactive Magnetorheological (MR) damper is investigated to reduce cable vibrations. The control-oriented cable-damper model is first established; a computer simulation for the cable-damper system is carried out; and finally a MR damper is experimentally used to reduce the cable vibration in a laboratory environment using a semiactive control algorithm. Both the simulation and experimental results show that the semiactive MR damper achieves better control results than the corresponding passive damper. Copyright © 2010 Techno Press.

This paper summarizes the updating of API RP 2A Recommended Practice for Planning, Designing and Constructing Fixed Offshore Platforms - Working Stress Design - API RP 2A-WSD 21 st Edition with Supplements 1, 2, and 3, to a 22 nd Edition. That 22 nd Edition is planned to be the last edition of API RP 2A-WSD. API RP 2A was due for a revisian. Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years. A complete and thorough review of the document was long overdue. The 21 st edition was issued in December 2000, Supplement 1 in December 2002, Supplement 2 in September 2005, and Supplement 3 in October 2007. In addition, API desired to incorporate the content from API Bulletins 2INT-MET, 2INT-DG, and 2INT-EX plus accommodate development and alignment of API Recommended Practices 2SIM, 2MET, 2EQ, and 2GEO with ISO. In the process of making editorial revisions, it became obvious that some technical revisions were also needed. Copyright 2010, Offshore Technology Conference.

Onshore LNG import and regasification terminals face potential environmental, permitting, cost and schedule issues that can be avoided by use of offshore floating LNG regasification units, FSRUs. The regas technology typically used in a FSRU depends on burning gas or utilizing open loop sea water for the source of heat of vaporization. Burning gas has an environmental impact to the air and the cost of consuming gas that could be sold. Using sea water imposes thermal and chemical impact on marine life. LNG Smart® Air Vaporization (SAV) is an alternative technology that transfers heat from ambient air to the LNG which reduces gas usage and air emissions dramatically, uses no sea water and creates no water pollution.

A financial analysis for an onsite facility to recover high purity propylene from refinery propane/propylene is put forward. The critical variables involved in the optimization of equipment sizes and operating costs for the recovery of high purity propylene by conventional distillation and distillation using a heat pump are examined. A capital cost estimate for each scheme and ranking based on an investment plus operating cost formula is then presented. Moreover, the discounted cash flow rate of return as a function of propylene value, utilities cost, and facility capacity is highlighted. The value of the PP feed stream is calculated as a function of the rate of return for the project and the other variables. This is an abstract of a paper presented at the 2011 AIChE Spring Meeting & 7th Global Congress on Process Safety (Chicago, IL 3/13-17/2011).

Academic libraries are reducing their holdings of print journals as more of this material becomes available electronically. Our work was motivated by the desire of the management at JSTOR, a major electronic archive of research journals, to preserve clean copies that retain full information accuracy from the vantage point of the researcher, but the broader community of librarians at research libraries is extremely concerned about this issue as well. We present results of a research project designed to provide guidelines and insight to JSTOR management and to the community of librarians at research institutions in this context. As a prelude, we report briefly on statistical analysis of defects in the pages of 25 journals for their entire publication history. This provides a backdrop for our approach to the problem. We then present models for two storage protocols, both of which have the goal of finding minimum-cost or Pareto optimal policies for ensuring, with a high probability, survival of at least one copy for a specified time horizon. One protocol involves archiving only clean copies in a secure environment, and the second protocol is a hybrid approach that combines clean copies with backup copies that can be cleaned up to replace clean copies that are lost or damaged. We also discuss other domains where our methodology can be applied. © 2013 Taylor & Francis.
